Immunity IEC60601-1-2
Test Test Level
Conducted RF
IEC 61000-4-6 3 V r.m.s
150 kHz ~ 80 MHz
80% AM (2Hz)
Radiated RF
IEC 61000-4-3 3 V/m
80 MHz ~ 800 MHz
3 V/m
800 MHz ~ 2.5 GHz
Note1: At 80 MHz and 800 MHz, the higher frequency range applies.
Note2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects, and people.
* Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones
and land mobile radio, AM and FM radio broadcast, and TV broadcast cannot be predicted theoretically
with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an
electromagnetic site survey should be considered. If the measured field strength in the location in which
the HBP-9020 is used exceeds the applicable RF compliance level above, the HBP-9020 should be
observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the HBP-9020.
** Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Compliance
Level
Potable and mobile RF communications
equipment should be used no closer to
any part of the HBP-9020 including
cables, than the recommended separation
distance calculated from the equation
appropriate to the frequency of the
transmitter.
Recommend separation distance
d = 1.2
d = 1.2
3 V r.m.s
d = 2.3
where P is the maximum output power
3 V/m
rating of the transmitter in watts (W)
according to the transmitter manufacturer
and d is the recommended separation
distance in meters (m).
Field strengths from fixed RF transmitters
3 V/m
as determined by an electromagnetic site
survey* should be less than the
compliance level in each frequency
range.**
